Using Snapshots
If for any reason standard portrait photos cannot be taken, you can increase the recognition
performance by using snapshots taken from the surveillance site. Possible scenarios may
include:
 Nighttime Recognition: where the installation site may not be subjected to IR LED
enrollment conveniently.
 Special Entities: who are unwelcomed or who refuse to comply with the standard
enrollment process.
 Frequently Misrecognized Entities: whose personal photos were not taken properly,
which leads to deficient recognition results.
To use snapshots from live videos, see 3.3 Snapshot of a Live Video.
To use snapshots from recorded videos, see 3.4 Video Recording. Capture the desired
image and use it as the source for face data enrollment.
To use snapshots from events, go to Event and Alerts and click Events. Right-click the
snapshot under Image (Snapshot of Events, Figure 5-17) and click Save image as… to save
the cropped image as the future source for face data enrollment. See 5.6.4 Events.
After the snapshots are saved, edit them so that they meet the requirements as specified in
5.5.1 Photo Requirements.
